# From Text Segmentation to Smart Chaptering: A Novel Benchmark for Structuring Video Transcriptions

We present <span style="font-variant:small-caps; font-weight:700;">YTSeg</span>, a topically and structurally diverse benchmark for the text segmentation task based on YouTube transcriptions. The dataset comprises 19,299 videos from 393 channels, amounting to 6,533 content hours. The topics are wide-ranging, covering domains such as science, lifestyle, politics, health, economy, and technology. The videos are from various types of content formats, such as podcasts, lectures, news, corporate events \& promotional content, and, more broadly, videos from individual content creators. We refer to the **paper** ([acl](https://aclanthology.org/2024.eacl-long.25/) | [arXiv](https://arxiv.org/abs/2402.17633)) for further information. We provide both text and audio data as well as a download script for the video data.

## Data Overview

### <span style="font-variant:small-caps;">YTSeg</span>

Each video is represented as a JSON object with the following fields:


| Field  | Description                                    |
|--------------|------------------------------------------------|
| `text`       | A flat list of sentences.           |
| `targets`    | The target segmentation as string of binary values (e.g., `000100000010`).              |
| `channel_id` | The YouTube channel ID which this video belongs to.          |
| `video_id`   | The YouTube video ID.            |
| `audio_path` | Path to the .mp3 file of the video.            |

| Partition  | # Examples    |
|------------|--------------|
| Training   | 16,404 (85%)   |
| Validation | 1,447 (7.5%)   |
| Testing    | 1,448 (7.5%)   |
| Total      | 19,229        |

### <span style="font-variant:small-caps;">YTSeg[Titles]</span>

Each chapter of a video is represented as a JSON object with the following fields:

| Field  | Description                                    |
|--------------|------------------------------------------------|
| `input`       | The complete chapter/section text.           |
| `input_with_chapters`    | The complete chapter/section text with previous section titles prepended. |  
| `target`     | The target chapter title.           |
| `channel_id` | The YouTube channel ID which this chapter's video belongs to.          |
| `video_id`   | The YouTube video ID which this chapter belongs to.            |
| `chapter_idx` | The index and placement of the chapter in the video (e.g., the first chapter has index `0`).  |

| Partition  | # Examples    |
|------------|--------------|
| Training   | 146,907 (84.8%)|
| Validation | 13,206 (7.6%)  |
| Testing    | 13,082 (7.6%)  |
| Total      | 173,195       |

### Audio Data

We provide audio files for all examples in the dataset, preprocessed into the .mp3 format with a standardized sample rate of 16,000 Hz and a single channel (mono). These files are organized within the directory structure as follows: `data/audio/<channel_id>/<video_id>.mp3`.

### Video Data

A download script for the video and audio data is provided.

```py
python download_videos.py
```

In the script, you can further specify a target folder (default is `./video`) and target formats in a priority list. 

## Loading Text Data

This repository comes with a simple, exemplary script to read in the text data with `pandas`.

```py
from load_data import get_partition
test_data = get_partition('test')
```

Equivalently, to read in <span style="font-variant:small-caps;">YTSeg[Titles]</span>:

```py
from load_data import get_title_partition
test_data = get_title_partition('test')
```

    abstract = "Text segmentation is a fundamental task in natural language processing, where documents are split into contiguous sections. However, prior research in this area has been constrained by limited datasets, which are either small in scale, synthesized, or only contain well-structured documents. In this paper, we address these limitations by introducing a novel benchmark YTSeg focusing on spoken content that is inherently more unstructured and both topically and structurally diverse. As part of this work, we introduce an efficient hierarchical segmentation model MiniSeg, that outperforms state-of-the-art baselines. Lastly, we expand the notion of text segmentation to a more practical {``}smart chaptering{''} task that involves the segmentation of unstructured content, the generation of meaningful segment titles, and a potential real-time application of the models.",
